We will get right to the point. Here is the Best Buy coupon for 10% off items in the categories listed below. You can print it off or just show it to them on your mobile phone. You can also keep it around because it doesn’t expire until January 31st, 2012. We’ll update this article as more recent coupons become available. Note that the code on the coupon is not unique so everyone can use it.

Original Article (no longer valid):

It’s not often that I buy stuff in stores because I can normally find the same item for much less online. I do, however, find myself turning to Best Buy on the rare occasion that I can’t fulfill my gadget addiction over the Internet.

Just a few months ago we moved from Iowa to Illinois, and when notifying the United States Postal Service (USPS) we received some coupons online. Among them was a Best Buy coupon that was 10% off of a single item from the categories I’ve listed below. Huh, I thought it was a pretty good deal since the coupon didn’t expire for about two-months.

Then I noticed that this particular coupon, like most others, was merely an image. The URL of the coupon is:

https://moversguide.usps.com/img/coupon/bestbuy/200804_clientarea.gif

The first thing that popped into my head was that part of the filename for the image is just the year followed by the month. In this case the 200804 represents April, 2008. As it turns out the URL of the image changes from month-to-month almost like clockwork. So the next time you’re looking to buy something from Best Buy check to see whether this coupon applies to you, and adjust the URL to represent the current month. USPS might be changing the URL as more people start to catch on, but by modifying the URL I can see that they’ve been using this structure for nearly a year.

For those of you who have a hard time reading the fine print here is a nice structured list of the things the coupon is valid for:
